Working Theory

Restore factory power and optimum fuel consumption as if your vehicle was new.

The oxygen sensor was developed in the late 60’s by Robert Bosch GmbH company. Today's computerized ECU systems rely on inputs from a variety of sensors to regulate engine performance, emissions and other fundamental functions. One of the key sensors in this system is the oxygen sensor. An automotive oxygen sensor is an electronic device used to measure the proportional amount of oxygen in the exhaust gas. All vehicles that were manufactured in the 80’s feature an oxygen sensor. The sensor is located in the emission-control system. When engine is running, the air fuel sensor delivers data to the ECU. The sensors must provide accurate information otherwise performance issues, increased fuel consumption and emission failures can result.

A functioning O2 sensor ensures that your engine is running at peak performance. Additionally, this sensor keeps your emissions in check and alerts you to when emissions are too excessive. For states that have vehicle inspection programs to regulate emissions, the use of the CEL and O2 light will alert officials to any excessive emissions. As a result, if one or more of your oxygen sensors is faulty during an emissions inspection for your car, you will most likely not pass the inspection.

Why replace? Failure of these exhaust air fuel sensors, either through normal aging, the use of leaded fuels, or due to fuel contamination with eg. silicones or silicates, can lead to damage of vehicle's catalyst and expensive repairs. Heavy exhaust alterations like catalytic converter bypasss, catless exhaust systems or headers trigger service light. In this instance the replacement of the exhaust gas oxygen sensor will not remedy MIL issues. If so, you need to wire up oxygen sensor simulator to the aftercat o2 sensor(s)' harness in order to get rid of Electronic Control Module limp mode causes the engine run inefficiently spoiling both pony and fuel efficacy.

exhaust gas oxygen sensors are recommended to be replaced after each 50.000 miles - 80.000 km.

Bosch air fuel sensors outperform any other brand in regards to reliability and durability. Oxygen sensors are used to reduce vehicle emissions, by ensuring that engines burn their fuel efficiently and cleanly. Robert Bosch GmbH introduced the first automotive lambda probe in 1976. The sensors were introduced in the US from about 1980, and were required on all models of cars in many countries in Europe in 1993. By measuring the proportion of oxygen in the remaining exhaust gas, and by knowing the volume and temperature of the air entering the cylinders amongst other things, an ECU can use look-up tables to determine the amount of fuel required to burn at the stoichiometric ratio (14.7:1 air:fuel by mass for gasoline) to ensure complete combustion. When an internal combustion engine is under high load (such as when using wide-open throttle) the oxygen sensor no longer operates, and the engine automatically enriches the mixture to both increase power and protect the engine.

Internal Design

The sensor element is a ceramic cylinder plated inside and out with porous platinum electrodes; the whole assembly is protected by a metal gauze. It operates by measuring the difference in oxygen between the exhaust gas and the external air, and generates a voltage or changes its resistance depending on the difference between the two. The sensors only work effectively when heated to approximately 300°C, so most lambda probes have heating elements encased in the ceramic to bring the ceramic tip up to temperature quickly when the exhaust is cold. The probe typically has four wires attached to it: two for the lambda output, and two for the heater power.

Operation of the Zirconia O2 Sensor

The zirconium dioxide, or zirconia, lambda sensor is based on a solid-state electrochemical fuel cell called the Nernst cell. Its two electrodes provide an output voltage corresponding to the quantity of oxygen in the exhaust relative to that in the atmosphere. An output voltage of 0.2 V (200 mV) DC represents a lean mixture. That is one where the amount of oxygen entering the cylinder is sufficient to fully oxidize the carbon monoxide (CO), produced in burning the air and fuel, into carbon dioxide (CO2). A reading of 0.8 V (800 mV) DC represents a rich mixture, one which is high in unburned fuel and low in remaining oxygen. The ideal point is 0.45 V (450 mV) DC; this is where the quantities of air and fuel are in the optimum ratio, called the stoichiometric point, and the exhaust output will mainly consist of fully oxidized CO2. The voltage produced by the sensor is so nonlinear with respect to oxygen concentration that it is impractical for the electronic control unit (ECU) to measure intermediate values - it merely registers "lean" or "rich", and adjusts the fuel/air mixture to keep the output of the sensor alternating equally between these two values. This type of sensor is called 'narrow band', referring to the narrow range of fuel/air ratios to which the sensor responds. The main disadvantage of narrow band sensors is their slow response: the control unit determines the exhaust gas composition by averaging the high and low swings in the sensor's output, and this process creates an inevitable delay Not quite sure this oxygen sensor fits your vehicle?

result exceeded expectations

I have to say that both the service and the result exceeded expectations. I was quite disbeliever but engine still runs a lot smoother and when I hit the throttle there is no hesitation and it takes off with surge of power, consumess noticeably less fuel. My only hiccup was the wiring since eco chip is NOT plug'n'play.

gains beyond my expectations

This was my 1st magnum purchase and it did not disappoint, I still duck one star. Fast shipping, a bit lousy packaging, straightforward directions for installation, top notch quality and gains beyond my expectations. The only regret was the kit dose not work in conjunction with my optimizer chip from (removed) so I had to uninstall it, in all other respects I was satisfied.

gave an extra 4 MPG

I bought a fuel economy combo from these guys and in my conclusion it works great mpg wise in addition not only did NOT kill my performance but a little bit improved it. This kit actually has brought my gas mileage back after I added cold intake and gave an extra 4 MPG. Bottomline I recommend it. Great value for your bucks.

gassing up much less fuel

after i set this economizer kit on my old celica with 250,000 mniles on it, i am gassing up much less fuel than before, there is no accurate calculation so its just a rough estaimte but these parts pumped up my economy by at least 15 %, did i lose power? - Nope!!!

I saw some mileage boost and fuel saving

Eco kit arrived promptly and package was as expected, magnum is a good supplier but changes in fuel economy were moderated or considerable MPG increase is a mere pipe dream. I saw some mileage boost and fuel saving that is appreicated but far from the claims advertized. Did notice a huge jump in acceleration though.

moderated level of economy improvement

Delivered right on cue, in good packaging and install it in two hours or a bit less. I see only moderated level of economy improvement only, as opposed to the 16% advertized. Another heads up to everyone, the intake add on requires certain modification of the intake, you have to drill the air filter cleaner's flange. I'm not delighted to perish OEM parts by fabricating. Engine pulls a little better and acceleration slightly improved but the car still remained underpowered.

fuel saver kit seems perfect in all areas

Part shipped sooner than I thought I should get. Have it installed by (removed) garage in (removed) and telling the truth, at the first peek I'm impressed by the extra mileage this kit delivered on my MX6. Havent noticed extra horses but the fuel saver kit seems perfect in all areas. I'd ultimately like to install on the wife's Cadillac too.

saw significant MPG gain

Installed this gas saver combo on my naturally aspirated Cougar and saw significant MPG gain. The lil horsepower gain that was advertized is no exception. I'm confident heaps of company could take the advantage of these parts like taxi companies, public transportation, police, airports. Although gas savers have conducted their job in my car for over years now, thus far there has been no compromise of durability and there are no setbacks at all. Cur runs like before, no check engine light, no bogging, engine revs up a bit better than w/o the kit and idles smooth. My summing up, this wrench-on combo is an easy way to get better mileage and a slight boost of performance. I'm bound I could extract even more from this engine both of economy and performance but my Cougar has 200K+ miles on it so I wouldn't venture to dust it. All in all I'd recommend to friends or family.

I can attest this kit worth every penny

I paired this fuel saver kit with my k&n filter and it works like a charm now I made 5 consecutive tests driving more than 1000 miles and I can attest this kit worth every penny and actually feel a difference in power and throttle response. Totally satisfied. %+ star purchase!
